Abstract
Abstract Use of additive manufacturing (AM) technology is quite mature in medicine and aerospace industries but adoption of the technology has been limited in the oil and gas industry. One of the reasons behind the slow adoption is the non-availability of industry standards and recommended practices. DNV aims to help the adoption of AM in the oil and gas industry by providing the needed industry standards and recommended practices. DNV is one of the largest classification societies in the world and provides classification, technical assurance, software and independent expert advisory services to the maritime, oil & gas and energy industries. DNV has been running several projects globally to help the industry qualify materials and products produced by additive manufacturing. DNV has been working since January 2018 together with main stakeholders in a joint Industry Project (JIP) to develop requirements necessary to introduce components made by AM for oil and gas and related applications. The outcome of the JIP was released to the industry in 2020; a standard that describes the qualification and quality assurance of AM parts. The AM technologies addressed in the standard are laser based powder bed fusion (PBF-LB) and wire arc additive manufacturing (WAAM). In this paper, the standard is presented, and a systematic way to qualify parts made by PBF-LB and WAAM technologies described. A case study, leading to a qualified part according to the standard will be presented. It has been led by Vallourec, a world leader in tubular solutions for the energy sectors. Vallourec embraced additive manufacturing a few years ago and is currently developing and offering WAAM components for various industries.
